  • the outer surface is formed by the lattice-shaped structure in conjunction with the sound-absorbing and / or sound-damping material and the inner surface by the continuous closed surface.
  • the attachment of the sound-absorbing and / or sound-damping material can be done by a pure pinching between the first and second part, wherein the connection of the first and second part can be done by means of screws. Likewise, clip connections, adhesive joints, or any other connections are possible. In addition, the sound-absorbing and / or sound-damping material may be glued or otherwise secured to one or both of the other parts.
  • An air flap 1 serves as an inlet flap for controlling the air inlet into the air duct system of a heating or air conditioning system of a vehicle.
  • the air flap 1 is arranged pivotably in an air channel about a pivot axis S.
  • the louver 1 is formed in several parts, wherein a first part 2 with a spherically curved surface and a arranged on the inside of the curvature of the first part 2, lattice-shaped second part 3 and formed by a foam material third part (not shown), between the first and second Part is arranged and adapted in its dimensions to the shape of the gap between the first and second part are provided.

  • both on the first part 2 inside and on the second part 3 on the side of the first part 2 dome-shaped projections 2 'and 3' are formed with openings into which screwed the screws become.
  • the first part 2 in addition to the two dome-like projections 2 'has a plurality of mutually parallel, stiffening ribs 2 "on the inside (see Fig. 3 ).
  • the dome-shaped protrusions 2 ' are presently arranged such that they are positioned between and connect two ribs 2 ", ribs 2" and dome-like protrusions 2' terminate in a plane which is also disposed within the curve.
  • the ribs 2 do not rest on the second part 3 as a result of the dome-shaped projections 3 'of the second part 3.
  • the first part 2 has edges 2'" which extend outward in the radial and axial directions and which seal the air flap 1 in the corresponding end positions.
  • the second lattice-shaped part 3 has in each case two webs 3 "which run parallel to one another and which intersect perpendicularly at web crossings (see Fig. 1 ), wherein all the webs 3 "end at a circumferential edge 3"', which extends in the radial and axial direction to the outside.
  • the edges 3 "'in the present case have a width which corresponds approximately to the length of the dome-like projections 3.
  • the edges 3" serve to cover the foam material and, in the assembled state, abut the inner surface of the first part 2.
  • the web width also corresponds approximately to the width of the edges 3 ", but the web thickness is much smaller.
  • the second part 3 has in the edge region a curvature of the webs 3 ", which corresponds approximately to the curvature of the inner surface of the first part 2.
  • the second part 2 is substantially planar, wherein the two dome-like ones of the substantially flat bottom surface
